SPECIFICATION forming part of Letters Patent N 0. 731,196, dated June16, 1903. Application filed October 27, 1902. Serial No. 128,983. (Nomodel.)

To all whom, it may concern:

Be it known that I, GILBERT MARTIEN,a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvementsin Gap-Nuts andSpring-Washers for Vehicle-Spindles; and I do declare the following tobeafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make. and usethe same.

My invention relates to improvements in cap-nuts and spring-washers forvehicle-spindles; and it consistsin the peculiar construction andcombination and arrangement of devices hereinafter described andclaimed.-

The object of my invention is to effect improvements in the constructionof a cap-nut for a vehicle-spindle and to combine therewitha washer anda spring to support the same and to compensate for the wear thereof toprevent endwise movement of the wheel on the spindle.

In the accompanying drawings, Figure l is sectional view of a cap-nutand spring-sup ported washer embodying my improvements;

showing the same in operative position on the spindle of a vehicle andbearing against the outer end of the hub of a Wheel thereon, a portiononly of the spindle and of the hub being shown. the cap 2, taken on theplane indicated by the line art of Fig. 1. Fig. 3 is a detail perspective view of the washer, and Fig. 4is a similar view of the spring whichoperates the washer.

In the embodiment of my invention I provide the cap-nut l, which may beeither of the form here shown or of any other suitable form, with anannular recess 2 on its inner side, in which recess is seated a spring3, which is here shown as a coil-spring. The annular recess 2 isconcentric with the recess 4: of larger diameter at the inner side ofthe cap-nut. In opposite sides of the recess or bore of the cap-nut arelongitudinal grooves 5, in which operate the radially-projecting spurs 6of the washer 7. The lattenis made of suitable metal and is of suitablethickness and size. This washer bears against the inner side of thespring 3 and is pressed thereby against the outer end of the hub of thewheel. As the Washer wears the spring Fig. 2 is a sectional view ofcompensates for the wear thereof, so that lost motion is prevented andany tendency of the wheel to move endwise on the spindle is obviated. Ashere shown, the outer ends of the grooves 5, in which the studs or spurs6 operate, are upset, as at 8, to close them; but the said grooves maybe closed at their outer ends by any other suitable means. In practiceand as here shown. I prefer to employ a washer 9 of the usualconstruction, which may be made of leather or any other suitablematerial, between the Washer 7and the outer end of the vehiclewheel-hub.

While the washer 7 is here shown as provided with a pair ofradially-projecting studs 6, I would have it understood that the numberof these studs may be varied, and I do not limit myself in thisparticular. The end of the spring 3, which bears directly against thewasher 7, is notched or recessed, as at 10, to receive one of the spurs6. Thus independent rotation of either the spring or the washer isprevented, the engagement of the studs 6 with the grooves 5 in thecap-nut preventing rotation of the washer 7.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be readily apparent, it is thought, without requiring amore extended explanation.

Various changes inthe form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new, anddesire to protect by Letters Patent, is-

1'. A cap-nut having a recess on its inner side and provided withlongitudinal grooves, in combination with a washer movablelongitudinally in said recess and having studs engaging said grooves,the outer ends of the grooves coacting with said studs to retain thewasher in the recess, and a, spring in the recess bearing against andengaged with the washer, said spring and washer having coacting devicesto prevent rotary movement of the spring, substantially as described.

2. A cap-nut having an annular recess on its inner side provided with alongitudinal groove closed at its outer end, in combinatlon with awasher movable longitudinally in In testimony whereof I have hereuntoset my hand in presence of two subscribing witbhe recess and having astud engaging said nesses.
